Question about 1999 Mercury Villager
I have 97 merc villager with 0ver 150K miles, which keeps overheating. The temperature gauage does not show it over heating, but you can just see the smoke coming out from under the hood after only driving about 5 - 10 miles. The fluids all look great, and as the car is idling it does not get that hot and there is no smoke. this only happens when you drive the vehicle. The smoke smells like antifreeze, if this helps. Also, the water pump is not squealing.
Sounds like a leakage, could be the hoses or the radiator. Check the upper and lower hoses, sometimes they become cracked from being old and over worked because hot fluids ran through all the time. Check the hose clamps making sure the hoses have not become corroded where the clamp keeps the hose on. If it looks okay check the hoses period making sure it is not leaking on your manifold or exhaust. If it looks fine check the radiator thoroughly. Also when checking the radiator make sure the the radiator does not wiggle, mine got hot and melted the top position rubbers that hold it in place from hitting back and fourth on the grill and fan. They are known to melt sometimes and might have to replace the rubber gaskets holding it in place at each end of top. You say it does not over heat and your red light does not come one and it drives great with good idle. It only shows smoke that smells like radiator fluid when you drive, it sound like a hose leaking and hitting the exhaust system.
If the radiator is leaking itself, there is a quick fix but you will eventually need to replace it. They have some stop radiator leak fluid at the local parts store.
I have used JB weld on some radiators as quick fixes as well, just until I could afford a used or new one.
This method will not work on hoses. If the hose is leaking from hose clamp, you should have enough hose to taper some off and re-clamp it. I would advise using new clamps when tapering or replacing the hose. If your hose is cracked further down the line then you will have to replace the hose.
Remember you will have 4 hose clamps, the ones that hook to the radiator and the ones that hook to the engine.
Good luck hope this helped some.
